The reaction of UO22+ with chromazurol S and the spectrophotometric determination of uranium in the presence of Septonex

Abstract

This work is concerned with a detailed study of the reaction of UO2+2 with chromazurol S in the presence of cationic tenside Septonex, which was found to be very promising of the group of cationic tensides. From the study were drawn a number of conclusions regarding the effect of the cationic tenside on the reaction of triphenylmethane dyes with salicylic acid groups with metal cations. Optimum conditions for the spectrophotometric determination of uranium with chromazurol S in the presence of Septonex were found.
